Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.00901 |
| Opus 5 | $0.00016 | $0.00451 |
| Sonnet 5 | $0.00007 | $0.00180 |
| Haiku 4.5 | $0.00003 | $0.00090 |
Grade A, and why
ot-ics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to ot-ics — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
OT / ICS Security
ACTION REQUIRED（读完后立刻执行）
NOW: 读取../field-journal/precedent-pentest.md— 工控环境误操作可致物理危害NOW: 书面授权必须写清：站点、网段、是否允许主动扫描/写寄存器NOW: case-init；默认 passive-first；ready_for_act前禁止对 PLC 写操作NEXT: tool-index；多数工控工具需手动与隔离实验网ACT: 资产与分区识别 → 暴露面 → 只读验证
适用场景
- 工控/SCADA/DCS 安全评估（授权）
- Purdue 模型分区与跨区通道
- Modbus/DNP3/S7/EtherNet/IP 等协议暴露
- 工程师站、HMI、历史库、跳板主机
- IT/OT 融合边界（防火墙规则、单向闸）
安全铁律（MUST）
MUST NOT 在未明确允许时：
- 对 PLC 写线圈/寄存器
- 全网高速率扫描生产 OT
- 中断安全仪表系统（SIS）相关路径
优先：只读识别、流量镜像、离线固件/配置分析
工作流
Phase 1 — 分区与资产
□ Purdue L0–L5 草图：现场设备 → 控制 → 监督 → 站点 DMZ → 企业
□ 资产清单：PLC/RTU/HMI/工程师站/历史库/Jump host
□ 协议与端口基线（仅授权网段）
Phase 2 — 被动与只读
□ SPAN/镜像 PCAP → protocol-reverse / Wireshark 工控解析器
□ 配置与工程文件离线审计（TIA/RSLogix 导出等）
□ 默认口令与明文协议（Modbus 无认证）记录为 Finding，不写盘改值
Phase 3 — 受限主动（仅授权）
□ 低速识别，维护窗口
□ 只读功能码优先
□ 每步 Evidence；异常立即停止并通报
Phase 4 — 固件/补丁面
□ 控制器固件版本 → CVE 映射（不盲刷固件）
□ 联合 firmware-pentest 做离线镜像分析
工具链
| 工具 | 用途 | 注意 |
|---|---|---|
| Wireshark 工控 dissectors | 被动解析 | 镜像流量 |
| Nmap NSE（受限） | 识别 | 速率与时间窗 |
| Claroty/Nozomi 等 | 资产发现 | 商业/现场 |
| PLC 厂商工程软件 | 配置审计 | 离线优先 |
| binwalk / Ghidra | 固件 | 离线 |

路由上下文
上游: MASTER R28
下游: 固件深挖 firmware-pentest；协议 protocol-reverse；IT 横向 windows-ad/attack-chain
同级: 不要用普通 Web 扫默认参数打 OT
任务完成自检
- 是否默认被动/只读并记录授权边界？
- 是否避免对控制回路写操作（除非明确允许）？
- Finding 是否含物理/过程影响说明？
- Checklist / journal？
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 6d ago First seen · 93 lines · 33 tokens per session scan A 81bf7ff97d1e
ot-ics is a skill published in the GitHub repository Saprophytic-seattle561/reverse-skill (1 stars, last pushed 2d ago), licensed MIT. It adds 33 tokens to every session and 901 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to ot-ics, differing in 0 lines, and is treated as a copy.
